Kennedy’s tweet comes in the wake of left wing outrage over Rush Limbaugh calling progressive activist and 30-year-old Georgetown University student Sandra Fluke a “slut” after her congressional testimony about her campaign for subsidized birth control.

Unlike Limbaugh, Kennedy has not apologized for his language, doubling down and stating, “Inhofe…sells the public interest for money.”

Kennedy calling him a prostitute, as the senator points out, means things are “improving.”

Rather than anger, Inhofe feels pity for Kennedy Jr. because he’s on the wrong side.

In an interview with KWTV News 9, the senator stated, “If you don’t have logic on your side, and you don’t have the truth on your side, you don’t have the science on your side, and you don’t have the votes on your side, all you can do is call names.”

The book reveals the real agenda of state control over the economy and personal behavior that is driving climate change alarmism. It also details the deliberate deception required to create an artificial policy consensus, and how the “Climategate” email scandal rocked the scientific community.

Those emails, leaked from the United Kingdom’s Climate Research Unit, a premiere global warming advocacy organization, noted that the data didn’t support the desired thesis that there is global warming. The emails also referred to how such data could be manipulated to affirm the thesis.

Of relevance to Robert Kennedy Jr., “The Greatest Hoax” also describes that Al Gore and other “global warming advocates” stand to personally benefit from the very government policies they support, within even the New York Times reporting on Nov. 2, 2009, that, “Critics say Mr. Gore is poised to become the world’s first ‘carbon billionaire,’ profiteering from government policies he supports that would direct billions of dollars to the business ventures he has invested in.”
